   To determine the directions of all the horizontal forces acting on crate 2 in the given scenario, let’s analyze the forces involved:

   1. Rope Force: The rope between crate 1 and crate 2 pulls crate 2 to the left.
   2. Cable Force: The cable connecting crate 2 to crate 3 pulls crate 2 to the right.
   3. Force from Crate 3: Crate 3 pushes on crate 2 due to the tension in the cable, acting to the right.
   4. Friction Force: Since the crates are being pulled across a rough road, there will be a frictional force opposing the motion, acting to the left.

   Given these considerations, the correct diagram will have the rope force and friction force both acting to the left, and the cable force and force from crate 3 both acting to the right.

   The correct answer is:

   (D) Rope ← | Friction ← | Crate 2 | → Cable | → Crate 3
